Agilent Technologies Inc. has announced a "first-to-market" technology that extends its end-to-end wireless analysis and troubleshooting solution femtocells, which access wireless networks via consumer broadband connections. The platform supports both standards-based and proprietary femtocell implementations.

Signaling Analyzer Real Time (SART) for Femto enables users to move quickly from the lab through trials to successful deployment, and then manage operations and scale for subscriber growth, according to Agilent. It provides a combination of detailed real-time diagnostics, troubleshooting and historic analysis.

Femtocells benefit both operators and subscribers in several ways. For example, they allow carriers to offload traffic from an outdoor macro network, which provides that network with more capacity and thus higher performance for subscribers. They also allow operators to reach subscribers in previously uncovered rural areas. Femtocells eliminate the attenuation that inevitably occurs as signals from macro towers pass through walls and surfaces such as the silver-coated windows characteristic of modern buildings. But there are many deployment and maintenance challenges, which, according to Agilent, SART for Femto meets by enabling users to:

• Properly dimension deployment and core network services;
• Evaluate femtocell performance in relation to third-party broadband connections;
• Interpret, correlate and analyse protocol messages on both sides of the gateway that connects femtocells to mobile networks in IuH implementations;
• Monitor within the IMS framework to identify calls related to femtocell access points in SIP-based IMS implementations;
• Identify femtocells in large structures with multiple mobile phones that overload the core network by attempting unauthorised access through femto;
• And examine problems that important customers have experienced in the past.

SART for Femto is already in use by several top-tier service providers around world on both standards-based and proprietary implementations.
